How a TKO is Assessed in Boxing

There are three ways a boxing match can end in a TKO victory. 

  • Referee Assessment & Decision 
  • Doctor’s Decision
  • Corner Intervention 
  • The Fighter

The referee is the predominant figure of authority in charge of calling a fight off. In boxing, they could step in for anything from a fighter receiving damage or being completely knocked out.

Referees will generally decide to call a fight off after a fighter is knocked down. If the ref feels that the fighter is compromised, they will rule the fight a TKO.

Doctors will also step in and call a fight for damage if they feel a fighter cannot continue. Usually, in between rounds or if the referee calls for assistance.

The corner of both fighters also holds the responsibility of protecting their fighters. They can call the fight if they feel a fighter cannot be won or their fighter is too injured.

But most importantly, the responsibility of the fighters relies on the fighters themselves. But they, more often than not, refuse to quit, which is why the other three must look after them.

In everything from kickboxing, MMA, and boxing, the responsibility of determining a TKO lands on three groups.

  • The Ref
  • Ringside Doctor
  • Fighter’s corners

The ref is the person most responsible for determining a TKO vs KO. It‘s the referee’s job to step in if a fighter cannot defend themselves or is taking too much damage.

The ringside doctor will determine a fight a TKO in two scenarios. Either the ref will ask the doctor to check the fighter, or the doctor checks fighters between rounds. If a fighter is too damaged to continue, it’s the job of the doctor to stop the fight.

Then there’s the fighter’s corner, which are also responsible for protecting their fighters. In between rounds, the main person in the corner can all the fight if they feel their fight is too damaged.

In boxing, the act of throwing in the tail is another way to call a fight off. Admitting defeat on behalf of their fighter in order to protect them.
